Production process of regenerated anti-static polyester staple fibers

Abstract

The invention relates to the field of fibers, and particularly discloses a production process of regenerated anti-static polyester staple fibers. The preparation method comprises the following steps:(1) raw materials are dried; (2) melting is conducted, specifically, the dried waste textiles and waste polyester bottle flakes are melted and filtered, then quenching and tempering treatment is conducted, and then secondary filtering treatment is conducted to obtain a filtered melt; (3) spinning is conducted, specifically, the filtered melt is subjected to spinning to form nascent fibers; (4) oiling is conducted, specifically, the nascent fibers are sequentially subjected to cooling, drafting for the first time, and oiling; (5) post-spinning is conducted, specifically, the oiled fibers are subjected to drafting for the second time; (6) shaping is conducted; and the polyester oiling agent in the step (4) is prepared from the components: hydrogenated castor oil polyoxyethylene ether, dinitrophenol, mineral oil, a thickening agent and fatty alcohol-polyoxyethylene ether. The regenerated polyester staple fibers prepared through the method have the advantage of being good in quality underthe good anti-static effect.

Description

technical field [0001] The application relates to the field of fiber, more specifically, it relates to a production process of recycled antistatic polyester staple fiber. Background technique [0002] Polyester staple fiber is a fiber obtained by spinning polyester into tow and cutting it, while recycled polyester staple fiber refers to the use of waste polyester bottle flakes after crushing and cleaning, the mixture of various raw materials is dried, melted and extruded, spun Silk, relaxed heat setting, cut to form recycled polyester staple fibers of different lengths, which belongs to the full utilization of renewable resources, has a lower cost and a broad market. [0003] Polyester is a kind of synthetic fiber widely used at present. It has superior physical and mechanical properties such as high strength, good elasticity, and high rigidity, as well as acid resistance and corrosion resistance.

AI Technical Summary

Problems solved by technology

[0003] Polyester is a kind of synthetic fiber widely used at present. It has superior physical and mechanical properties such as high strength, good elasticity, and high rigidity, as well as acid resistance and corrosion resistance. However, polyester molecules are bound by covalent bonds, which can neither be ionized nor Unable to transfer electrons, it is very easy to generate and accumulate charges, causing polyester to easily generate static electricity

[0004] In view of the above-mentioned related technologies, the inventor believes that there are polyester staple fibers in the process of preventing silk, because the friction between the fiber and the metal and the friction between the fibers are relatively large, so that a large friction will be generated in each spinning process. Static electricity makes the fiber easy to fluff, pilling, dust, etc., and even makes the quality of the produced polyester staple fiber worse
